Hi Brian,
Polymorph is a low-fusing temp thermoplastic that can be moulded by
hand or hot air.
http://www.mutr.co.uk/prodDetail.aspx?prodID=576gives some info and ordering although I bought it at maplins in the
UK.
To stop the wobble...
The HP stubby pen holder on the 7475A has enough structure to firmly
hold the pen ∗if∗ pressure can be applied to the pen to hold it
against the holder.
I tried the traditional elastic band but this couldn't handle the
torque and the pen wobbled.
I then tried the polymorph by using it to force and hold the pen into
position when set...so far it has worked well.
I will put photos of what it looks like.
The stylus was created from an old stubby pen holder and a tile
scribe/cutter with a solid tungsten carbide bit bought at wickes in
the UK.
Hope this helps?
regards PK.
